Red Line: US seeking evidence of chemical weapons in Syria before taking action

Having previously stated that the use of chemical weapons by the regime against the Syrian people would be a "red line", US President Barack Obama announced that more substantial evidence is needed before any decisive action is taken

He said that he has been very clear publicly that the Syrian Government used chemical weapons on its people and crossed a line that will change his calculus on how the United States approaches these issues.

According to Fox News, much has been talked after Obama suggested that the use of deadly chemical agents could be the 'red line' for the U.S. to intervene in the two-year-old Syrian war.
